What Is a Condenser Microphone: An Essential Guide to Condenser Mics

If you’re new to audio engineering and sound mixing, you might find yourself in a doozy over the large number of microphones available on the market. Have you ever wondered: what is a condenser microphone?

Which microphone works for what purpose and which one is best suited for your needs. The answer, as usual, depends entirely on you.

Steely Dan’s producer Gary Katz spent years testing different mics and instrument combinations until he found the best ones for each instrument.

You don’t have years and loads of cash to do that so today I’ll attempt to set you on the right path when it comes to mic choice. This guide is a brief introduction to condenser microphones.

WHAT IS Condenser Microphone

What Are Condenser Mics?

Condenser microphones are far more sensitive than dynamic mics. This sensitivity makes them appropriate for recording acoustic instruments, as well as capturing ambient sounds in a room.

Direction is separate from the mic type. Condensers and dynamics both come in cardioid, omnidirectional, and other patterns. A cardioid mic favors what is in front of it. An omnidirectional mic picks up around it. A cheap dynamic is often cardioid, not open to the whole room.

Condensers are a common choice for vocals, acoustic guitar, and sound at a distance — say, a choir or an orchestra — because they pick up detail, not because every condenser is more directional than every dynamic.

I’ll talk about the condenser microphone, what it does and how it differs from a dynamic mic. I’ll also discuss which uses they are best tailored for.

Lastly, I’ll mention a few condenser microphones that I think are worth it and what you should consider when buying one.

First up, here are a few condenser mics you can buy. Prices move, so treat the figures below as a snapshot:

What Is A Condenser Microphone?

A condenser microphone turns sound into a signal with a capacitor. A thin diaphragm sits close to a charged backplate, and sound moves the diaphragm, which changes the capacitance. That change becomes the audio signal. You’ll mostly find this design in recording studios. Compared with a typical dynamic mic, it usually captures a wider frequency range and finer detail.

Condenser microphones have a great transient response. In essence, it means that they can better capture the authentic sound of an instrument and its speed.

A condenser is sensitive, so a quiet source still produces a usable signal and the mic can catch the nuances of a performance. That is not the same as being built for louder sounds. A loud source can overload it if you exceed the mic’s maximum SPL. Assuming your performer knows their instrument front and back, of course.

Most studio condensers need phantom power, commonly 48V, from a mixer, audio interface, or external supply. The voltage is high, but the current is only a few milliamps, so it is not a heavy power draw. USB condensers and some electret mics are powered another way, so check the model before you assume it needs 48V.

Studio recordings often sound more nuanced and crisp partly because condensers are common there, in a controlled room. They are not limited to the studio. Condensers are used live for vocals, choirs, and acoustic instruments. A handheld model such as the Neumann KMS 104 Plus is built for the stage.

Dynamic microphones are more rugged, so they are the usual choice when a mic will be grabbed, dropped, or kicked. If a dynamic mic takes that hit, it’ll likely still work. A condenser is more likely to be damaged by the same treatment.

Condenser Mic – What You Need to Know

The flip side to all of this is that they aren’t on par with condenser mics recording quality. They don’t have nearly the same frequency range or transient response.

So if you’re wondering why do most live recordings of your favorite songs not sound as good as the studio version, this is it. So be sure to give the musicians on stage a break.

One last difference between the two types of mics is that dynamic ones don’t require as much power to operate. So they’re far easier to set up and get rolling. One more reason to use these for live recording is convenience.

One more thing about condenser microphones is that they’re far more expensive than dynamic microphones.

I’m sure someone will mention that you can find condensers at a more affordable price. That’s true, but keep something in mind.

Cheaper condensers vary. Some are noisy or harsh, but a decent budget condenser does not automatically add a lot of distortion. If you’re starting out, a known entry-level model is a reasonable way to learn the type.

What Are The Types Of Condenser Mics?

There are two types, small-diaphragm ones, and large-diaphragm microphones. What’s the difference?

Well, small-diaphragm mics are best suited for recording string instruments since they offer the best wide-frequency recording.

Meanwhile, large-diaphragm mics are best suited for vocals since they add a layer of warmth to whatever you’re recording. Of course, be careful with distortion that could be caused when you emphasize certain sounds.

In general, I reach for a small-diaphragm mic when I want a neutral, detailed capture, and a large-diaphragm mic when I want more warmth on a voice, including a voiceover. You could always test both so you get a better feeling for what each one’s strengths and weaknesses are.

What Are The Best Uses For Condenser Mics?

While the specifics are more complex than a simple use this for this and that for that, there are some general rules of thumb.

If you are recording high-frequency instruments like acoustic guitars, electric guitars, pianos and woodwind instruments, especially, these are best suited for condenser microphones.

On the other hand, close-miked drums, especially kick and snare, are often recorded with a dynamic microphone. Those mics take high sound pressure and rough placement well.

A loud source can distort a condenser if you go past its maximum SPL. It does not automatically damage the diaphragm. Condenser overheads and room mics are a normal part of a drum kit. Use a pad, or give the mic more distance, when the source is very loud.

What Should I Consider Before I Buy A Condenser?

Well, on top of everything that I already mentioned there are a few specificities you need to put into consideration.

Polar patterns: these dictate how much your mic can pick up. Some mics can pick the solitary sound of an instrument.

Meanwhile, others can pick the sound of an entire band. Make sure you read the polar pattern of a mic to know what it can and can’t pick up. Some mics offer you the option to switch the pattern depending on your specific needs.

“But I don’t know how to read patterns.” you might say and to that, I respond, “Don’t worry, I got you covered.” there are only a handful of things you need to memorize.

Cardioid pattern: It means that a mic can only pick what’s in front of it. This is perfect for recording a single instrument or a vocal performance.

Bi-directional

This one means that your mic can pick what’s in front of it and what’s behind.

This one is useful for dual uses. If you have two vocal performers sharing the same mic, for example. Think of David Bowie and Mick Ronson’s Top of the Pops performance of Starman.

Omnidirectional

think of it as panorama mode but for audio recording. You can record sounds at 360 degrees. This is perfect for recording the ambiance of the recording room. John Bonham’s drum intro to When the Levee Breaks comes into mind.

Other than the patterns, there’s one thing I recommend you pay attention to.

Sensitivity

Air pressure greatly affects what your mic captures. If you want dense soundscapes in your recording, highly sensitive mics are the way to go. Just don’t take them to a live performance.

The higher the sensitivity the more your mic picks up. This means that your recording environment should be equally controlled.

What Are The Best Condenser Microphones?

While I can’t definitively answer that question, I can recommend a few good mics. We’ll split it into 2 categories. First, we have large diaphragm mics.

Audio Technica AT2035

For your first large-diaphragm mic, AudioTechnica is offering a great introduction to this type of mic for a more than affordable price. It is a fixed cardioid condenser, so it favors the source in front of it rather than offering switchable patterns.

The mic comes with a custom shock mount and a protective pouch for extra protection. In terms of performance, it’s not bad at all. Self-noise is low for the price: AudioTechnica rates it at 12 dB SPL.

AudioTechnica did a splendid job designing the AT2035. With its matte black finish and streamlined controls, it certainly looks far more expensive and professional than its price tag would imply.

Speaking of price, AudioTechnica priced the AT2035 at a very reasonable price tag that fits most budget levels. If you want to pick up your first large-diaphragm mic but are afraid of investing too much, this is a great first tryout.

Now for my small diaphragm mic recommendation.

Rode NT5 Matched Pair

Rode has a reputation for making great mics at affordable prices. The best offering they have for small diaphragm mics, in my opinion, is the Rode NT5 matched pair.

Why get one mic when you can have two quality mics. In terms of performance, this one is a winner.

It’s able to capture complex sounds incredibly well and with low distortion. Similarly, it’s a great choice if you want to record string instruments.

It gives a bright and crisp sound that’s not usually found in this price range. These mics are preferred by people who want to mic stereo sound.

They are nicely designed as well, giving off a professional look and feel. The sleek metal design is a favorite of mine. Rode priced these babies very reasonably and it’s a sweet deal if you ask me.

Overall, if you’re looking for reasonably priced small diaphragm mics with great performance these are for you.

What Is Condenser Microphone – In Conclusion

There are no perfect mics for each case and there are certainly no perfect mics for every case.

Microphones, much like cameras, are unique equipment that require some experience and familiarity with in order to squeeze the best performance out of them.

You’ll need to experiment with a few mics at the very least before you find what’s perfect for you.

Hopefully, this guide has eased you into condenser mics and has given you an idea of what you need to consider and look for when buying one.

The rest is on you: you can now find a mic that works best for your needs. Good luck.
